PROBLEM TO BE SOLVED: To provide a liquid-filled lens for ophthalmic applications.SOLUTION: A variable focus lens apparatus includes at least one rigid optical disc, at least one flexible optical membrane and at least one layer of transparent fluid that is in a communication state with a fluid channel and a reservoir. When incorporated in a spectacle lens, a lens system enables wearers to adjust refractive power of each lens, so as to achieve preferred binocular visual performance, consistent with maximum three-dimensional lift degree and binocular fusion at any desired object plane. |
